WASHING-MACHINE.

SPECIFICATION forming m of Letters Patent No. 349,747, dated September28, 1886.

Application filed April 1, 1886. Serial No. 197,480. (No model.)

To all whom it may concern.-

Be it known that I, JOHN W. RIOKER, a citizen of the United States,residing at Chelsea, in the county of Suffolk and State ofMassachusetts', have invented certain Improvements in \Vashing-Machines,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, making part of thisspecification, in which Figure 1 is a front elevation of my improvedwashingmachine. Fig. 2is a transverse vertical section of the same onthe line m of Fig. 1. Fig. 3 is a longitudinal vertical section throughthe center of the base of the machine,

tub and its fastening-plate.

illustrating my improved method of securing it in place within awash-tub. Fig. 4 is a horizontal section through one end of the base ofthe machine and the adjacent portion of the Fig. 5 is a plan of theopposite end of the base and the fasteningplate used in connectiontherewith; Figs. 6, 7, and 8, details in perspective. Fig. 9 is aperspective View of one of the bed-rollers.

My invention relates to certain improvements in washing-machines; and itconsists in certain novel devices for firmly securing the machine withinthe wash-tub, as hereinafter set forth and specifically claimed.

In the said drawings, A represents the base of the machine, from whichrise two standards or end pieces, B B, which are provided with verticalslots for the reception of thehorizontal shaft I) of the main roller 0,which is fluted and adapted to be rotated by the handled, the rollerbeing kept down in place by elastic bands 6 at the ends of the machine,each band passing over a movable piece,f, bearing on the shaft 1), and astationary projection, g, secured to the adjacent standard 13. Thesedetails of construction, however, form no part of my present invention,and will not, therefore, be further de scribed. The main roller 6 is oflarger diam-. eter at the center of its length than at the oppositeends, being tapered on a curve from the center toward each end, whichgives its surface a convex form in the direction of its length, as seenin Fig. 1, this convexity of the surface causing the clothesto maintaina central position as they pass through the machine, and effectuallypreventing them from working toward either end of the roller, andthereby clogging the mach ine,-as would be liable to suitable recessesin the standards B. The rods '5 are parallel to each other and to theaxis of the main roller 0, and are so arranged that the curvature of thebed will correspond approximately to the transverse curvature of theexterior surface of the main fluted roller O,whieh is kept downupon thebed by the action of the rubber bands 6, which yield to allow of the passage of the clothes or other articles to be washed between the roller 0and the roller-bed there 7 under. The rods t are connected together by aseries of bridge-pieces, a, through which they pass. These pieces aextend transversely across the machine and serve as division-plates toseparate the contiguous rollers D of each row. Rods 7c are alsoprovided, which .pass through the bridge-pieces a beneath the rollersand serve to stiffen and re-enforce the rods The surface of each rolleris composed of a series of con tiguous flattened portions orparallelograins, m, which extend longitudinally from one end to theother of the roller, the angles of intersection of the flattened facesat forming corners or edges n, upon which the main fluted roller 0 acts,whereby all liability of slip is prevented and the positive rotation ofthese rolls thus insured, as well as the positive feed of the clothesthrough the machine, which is not always the case with the ordinaryrolls of circular form in cross-section, on account of the liability ofthe main roller to slip over the wet and soapy Surface of the clotheswithout rotating the smaller rolle rs,which results in the failure oftheclothes to pass through the machine.

The rollers D may be of any suitable length and of octagonal form incross-section, as shown, or of any other suitable polygonal form, togive their Surfaces any desired number of fiat faces or sides.

' The machineis adapted to be secured in place within an ordinarycircular wash-tub, G, Fig. 3, in the following manner: On the inside ofthe tub, at points diametrically opposite to each other, are secured, bymeans of screws, metallic fastening-plates I K, for the reception of theends of the base Avof the machine. The fastening-plate I is providedwith upper and lower flanges or lips, 19 q, between which one end, 0, ofthe base A is placed, two horizontal pins,s s, projecting from the plateI, entering corresponding sockets or apertures,t, formed in the ends 7'of the base A, and preferably provided with metallic bushings v, theflanges p q and pins 8 thus serving to securely support and confine thisend of the base and prevent any lateral or vertical movement of thesame. The opposite end, w, of the base rests upon a flange, a, at thelower edge of the plate K, which is provided at its center with twoprojections, b 0, one above the other, the lower one, I), entering aslot, d, in the end to of the base A,whereby the latter is steadied andprevented from moving laterally, while the upper one, 0', is

located above the level of the upper surface of the base A, to which ispivoted a latch, M, having an inclined outer edge, e, which fits be:neath the projection c, as seen in Figs. 3 and 5, andthus serves to lockthe base securely and. immovably in place, the inclined surface 6 actingas a wedge to tighten the parts by exerting a downward pressure on theend w of the base A, to which it is pivoted, the latch being easilyswung around on its pivot by taking hold of the projection or handle fon its upper surface.

secure by Letters Patent, is-

The combination, with the base A, provided at one end with the sockets tand at the opposite end with a slot, (1, of the fastening-plate I,adapted to be secured to the inside of the washtub, and having theflanges p q and the horizontally-projecting pins 8, adapted to enter thesockets t, the fastening-plate K, adapted to be secured to the inside ofthe tub, opposite to the plate I, and having the flange a and theprojections b c, the latter projecting above the level of the uppersurface of the base A, and the latch M, pivoted to the base A,andadapted to be swung under the projection c, all operating substantiallyas and for the purpos'e set forth.
